Has anyone else noticed a dramatic improvement in the accuracy of time
of day on iPhones and iPads since the release of iOS 8.2? The accuracy
used to be only plus or minus 2 or 3 seconds, now it is about 100
times better, usually a few tens of milliseconds. I figure Apple might
have finally paid some attention to accurate time of day with 8.2,
possibly because of the Apple Watch. It's a pleasing improvement, I
hope it's permanent.

====================================
I noticed something similar on my iPad, but hadn't correlated the change
with iOS 8.2. I thought it was just chance, but you could be right. On the
other hand, I just checked now and it's 1.9 seconds off. I compare with
Emerald Time, which includes my one stratum-1 NTP server in its sources.
